Elastic acetabular anchoring brace for hip acetabular joint insert made of rigid material

摘要

The flexible acetabular mounting (1) for a rigid replacement hip socket has deformable collars (3) divided into petals by transverse slits. These fold back over the outer surface of the mounting when it is inserted into the acetabular cavity and act as a shock absorber, reducing ovalisation and torsion in the cavity.
